<span>I believe the answer is B)Diuretic therapy
</span>
The patient has alkalosis(pH 7.49), increased respiratory rate (20/min) and decreased carbon dioxide level(<span>pCO2 30). These findings point to respiratory alkalosis. 
The reason for increased respiratory rate probably because of heart failure that is shown by the decreased </span>cardiac index, pO2, <span>crackles, and wheezes. The treatment for congestive heart failure is to decrease the preload and blood pressure by giving a strong diuretic like furosemide.</span>

Q2. Which formula represents a homogeneous mixture?
bija089 [108]

Answer:

D) HCl(aq)

Explanation:

A homogeneous mixture can be defined as any liquid, solid or gaseous mixture which has an identical or uniform composition and properties throughout any given sample of the mixture. In Chemistry, all solutions are considered to be a homogeneous mixture.

In this scenario, the chemical formula which represents a homogeneous mixture is aqueous hydrogen chloride, HCl(aq). The aqueous hydrogen chloride is a homogeneous mixture of water and hydrogen chloride. This ultimately implies that, aqueous hydrogen chloride HCl(aq) is a solution of hydrogen chloride in water and it is commonly referred to as Hydrochloric acid.

Given by the chemical equation;

HCl(aq) + H_{2}O(l)  →  H_{3}O^{+} (aq) + Cl_{−}(aq)
